Learning objectives
The learning objectives for this exercise are:
- Describe and identify the mechanisms by which variation arises and is fixed (or lost) in a population over time.
- Explain how the processes of drift, natural selection, migration, and mutation can affect the elimination, maintenance or increase in frequency of alleles in a population.
Exploring the assumptions of HWE
Mechanism of selection
- Moving population average
- Drift vs. selection- Effect of sample size on selection and drift in phenotypic evolution
- Drift as sampling error
- Drift has a larger effect in small populations
Populations have significant underlying variation
Intuition of moving mean
